本文阐述采用粉末冶金热压烧结工艺,研制难熔金属钽基自润滑复合材料及其应用。讨论了该材料在大气中的摩擦磨损特性以及材料润滑相的结构分析。将该材料加工成保持架,在高真空条件下进行了轴承寿命试验;结果表明,保持架综合性能良好,可有效地提供润滑该类轴承的润滑条件。 This article describes the use of powder metallurgy hot pressing sintering process, the development of refractory metal tantalum-based self-lubricating composite materials and their applications. The friction and wear properties of the material in the atmosphere and the structural analysis of the lubricant phase are discussed. The material is processed into a cage, the bearing life test under high vacuum conditions; the results show that the overall performance of the cage is good, can effectively provide lubrication of such bearings lubrication conditions.
